Israeli Prime Minister Benjamin Netanyahu said Sunday that Israel stood in solidarity with the people of Iran as protests rocked several cities in the Islamic republic this week.

"We stand in solidarity with the struggle of the Iranian people and with their aspirations for freedom, liberty and justice," Netanyahu said at the weekly cabinet meeting.

Syrian Kurdish leader Mazloum Abdi was in Damascus on Sunday for fresh talks with officials on integrating his forces into those of the central military, the Kurds' armed forces said.

At least 80 troops from Yemen's secessionist Southern Transitional Council (STC) have been killed in fighting with Saudi-backed forces and strikes since Friday, a military official from the group told AFP on Sunday.

Saudi-backed troops on Saturday made advances in Yemen's resource-rich Hadramawt province, military officials said, as confrontations between forces backed by Riyadh and Abu Dhabi have triggered a deep rift between the two Gulf allies.

The U.N. said Thursday that a Palestinian boy in the Gaza Strip drowned in floods that engulfed his tent camp, with videos showing rescuers trying to pry his body out of muddy waters by pulling him by the ankle. It was the latest sign of the miseries that winter is inflicting on the territory's population, with many left homeless by the devastation from two years of war.

Health officials also reported the death of another 9 year-old boy in Gaza Thursday, but the circumstances were not clear.

Yemen's transport ministry, which is aligned with Emirati-backed southern separatist authorities, on Thursday said Saudi Arabia has imposed requirements mandating that flights to and from Aden International Airport undergo inspection in Jeddah.

The ministry, which is affiliated with the Southern Transitional Council, or STC, said in a statement that it was "shocked" by what it denounced as "sudden procedures" requiring international flights departing from or arriving in Aden to stop in Jeddah for inspection before continuing their journeys.

Airstrikes killed seven people in Yemen on Friday as a Saudi-led coalition attacked UAE-backed separatists who have seized huge swathes of territory, an official for the group.

More than 20 people were also wounded as seven airstrikes hit a camp in Al-Khasah, said Mohammed Abdulmalik, head of the separatist Southern Transitional Council in Wadi Hadramaut and Hadramaut Desert.

Yemen's Hadramawt province has launched an operation to "peacefully" take back military sites after a sweeping advance by UAE-backed separatists, its governor said on Friday.

"This operation is not a declaration of war, nor an attempt to escalate tensions," Salem Al-Khanbashi said in a statement reported by the official Saba Net news agency, shortly after he was also appointed to lead the Saudi-backed National Shield forces in Hadramawt.

Separatists from Yemen's Southern Transitional Council said on Thursday that Saudi-aligned government forces would enter territories seized by the UAE-backed group, in a step that appeared unlikely to satisfy Riyadh after it repeatedly demanded their full withdrawal.

The United Arab Emirates announced on Tuesday the withdrawal of its remaining forces in Yemen after Saudi Arabia earlier set a 24-hour deadline for their departure.

"The Ministry of Defense announces the termination of the remaining counterterrorism teams in Yemen," a statement from the ministry said, adding that Abu Dhabi made the move "of its own volition, ensuring the safety of its personnel, and in coordination with relevant partners."
